GSO 10" F4 Truss

Hello all long time no post, can anyone advise me, I just received my new scope which is bit light on documentation but how do you adjust the primary on these things, I noticed the 3 Allen keys bolts at the primary end with the 3 grub screws, I assume you release the grub screws before adjusting the main Allen key bolts, but I may be wrong, wouldn't be the first time :D

Hi Trevor,


I have a 12" one of these in storage. From memory the smaller grub screws are the locking screws and the larger are the adjustment screws.



You might to take a look around the site for a few reviews and some mods you will need to undertake to get it working well. The secondary cage needs reinforcing and focuser board will need to be beefed up to hold heavier loads. You'll need a shroud to prevent stray light and of course the focuser is not up to snuff either. The rest is ok though.
